Definitions

  • Flywheels are generally energy storage devices.
  • a historical application example of a flywheel as an energy store is the flywheel used in the so-called Girobus in the 1950s.
  • a steel flywheel weighing approximately 1.5 tons with a usable energy content of approximately 4.5 KWh was provided.
  • the useful energy content related to the rotor mass is only approx. 3 Wh / kg with the Girobus whereas theoretically an energy density of approx. 60 Wh / kg could be achieved with steel regardless of the safety aspects.
  • flywheels of the type mentioned were known. These new flywheels have a number of advantages over conventional steel flywheels, such as higher peripheral speeds (approx. 500 m / s) with the resulting higher energy density (approx. 20-80 Wh / kg rotor) and extremely safe behavior when bursting.
  • This property is mainly explained by the fact that in the event of a burst, approximately 95% of the rotational energy is converted into deformation energy (ie into heat) and only approximately 5% of the rotational energy has to be absorbed by a protective housing.
  • the requirement for that Protective housing is also further simplified because flywheels made of fiber materials break down into thousands of small particles when they burst. In contrast, a flywheel made of solid steel breaks into a few pieces when it bursts.
  • flywheels made of fiber materials Due to the fact that the circumferential speed of flywheels made of fiber materials is 10 times higher than that of conventional steel flywheels, the mass is reduced by a factor of 100 with the same energy content, i.e. For example, from 1200 kg for steel to 12 kg for fiber material, which significantly simplifies the requirements for rotor bearings.
  • flywheels made of high-strength fiber materials have a wax part which is directly relevant to practical use, namely the high production costs.
  • All previously known flywheels of the type mentioned are reinforced with single fibers or fiber yarns. They require a complex winding process with precise fiber guidance or with a tension preload that depends on the winding radius. Only the plastic matrix consisting mainly of epoxy resin is used to connect the fibers to one another and to absorb the radial tensile forces occurring during rotation.
  • the proposed flywheel according to the invention has the one defined in the characterizing part of patent claim 1 Characteristics on. Since the fibers of the reinforcement as such already form a bond with one another, the stress on the plastic matrix is reduced at high speeds. In addition, the winding process is simplified and possibly accelerated because the guidance of a tape or a strand requires less technical effort.

Abstract

On connaît depuis 1970 des volants de matériaux en fibres (par exemple, verre, polyaramide) qui ont certains avantages par rapport aux volants en acier, par exemple une densité d'énergie plus grande et un comportement à l'éclatement pratiquement sans danger. Jusqu'à présent, les volants obtenus par bobinage de fibres furent fabriqués exclusivement à partir de monofilaments enrobés d'une matrice synthétique (par exemple, la résine époxyde). Cette opération d'enroulement est compliquée et exige, entre autres, un guidage précis des filaments. Pour obtenir le volant selon l'invention, une bande de tissu de filament (par exemple verre, polyaramide) est enroulée avec précontrainte sur un moyeu. La précontrainte est modifiée en fonction du rayon d'enroulement qui augmente. Les couches d'enroulement sont imprégnées d'une résine synthétique (par exemple, résine époxyde) pour leur fixation. Après achèvement de l'enroulement, le volant est durci en le tournant et en amenant de la chaleur sous vide. Le coût de l'enroulement et aussi du volant terminé obtenu à partir d'une bande de tissu en filaments est considérablement diminué par rapport aux volants en monofilaments.
